Abstract: Fracturing design is the core of hydraulic fracturing technologies. The particularity of unconventional reservoirs brings about challenges to the fracturing design. In this paper, the development direction of fracturing design was analyzed after new models and methods for fracturing design all over the world were investigated. These new models and methods mainly involve reservoir description, and fracture depiction, optimization and simulation. Reservoir description mainly involves a new geomechanical model built based on the acquisition of innovation parameters. Fracture depiction focuses on new method development to increase the accuracy of the existing monitoring means based on physical simulation experimental results. Progress in fracture optimization focuses on the interaction between reservoirs and fluids and the development of new numerical reservoir simulation models on the basis of law description. Hydraulic frac-ture stimulation involves the research and development of new numerical fracture simulators suitable for multi-stages and multi-clusters fracturing in horizontal wells by means of innovative methods. It is strongly recommended to strengthen basic research and try to realize breakthroughs in terms of various evaluation models and software so as to improve the quality of fracturing design and develop uncon-ventional resources efficiently and economically in China while the investment on tools and equipments are guaranteed.
